I just began load development on a new rifle/ barrel (6 creedmoor, 26" proof barrel). I am following Erik Cortina's PRS load development advice where he tested primer & powder combos using a 10 shot method.
I realize that 1 shot for each powder charge is not enough statistical evidence to draw a full conclusion, but it should show a pattern and that's where my question lies. I am testing 105 berger boat tails (not hybrids) vs Barnes 112 match burners and also testing h4350 vs n550 as I've been able to obtain some n550 and my h4350 supply is dwindling. The test results show that h4350 to spike and plateau in terms of velocity whereas the n550 is more linear and flatter in this regard. I was not shooting for groups at all but The n550/ 112 match burner combo shot lights out event with the different powder charges but had a lower velocity. Is the flatter, more consistent nature of the n550 a good thing or does this display a lack of a node and would I be better off selecting a charge within h4350's plateaus? Thanks
